Problems solved by technology

However, as in JP2009-263567A, there is a problem that the antistatic function is lowered when the compound having conductivity is dissolved in an appropriate solvent such as methanol or ethanol and coated.
Although the cause of this is not clear, it is assumed that it is because, due to the appropriate solvent coordinating the compound having conductivity, the distance between the compounds having conductivity is lengthened since the compound having conductivity is mixed too uniformly with the binder and ion conducting and electron conducting is not made excellently.
The major axis wh

[0398]Preparation of Optical Film

[0399]As shown below, optical film samples 1 to 43 and 54 to 66 were prepared by the antistatic hard coat layer forming composition (coating solution) being prepared and the antistatic hard coat layer (referred to below as “hard coat layer”) being formed on the transparent base material.

[0400]Synthesis of Ion-Conducting Compound (Conductive Polymer) (a) IP-15

[0401]As a compound corresponding to (A-2) in JP4600605B, IP-15 (30 mass % of ethanol solution) which was a quaternary ammonium salt-containing polymer which has an ethylene oxide chain was synthesized in the same manner as the synthesis example 2 in the patent document. The weight average molecular weight measured using GPC was approximately 200,000.

[0402]Synthesis of Ion-Conducting Compound (a) IP-16

[0403]As a compound corresponding to (A-5) in JP4678451B, IP-16 (30 mass % of ethanol solution) which was a quaternary ammonium salt-containing polymer which has an ethylene oxide chain was...

[0508]Preparation of Hollow Silica Dispersion Solution B-1

[0509]With regard to 500 parts of the hollow silica dispersion solution A-1 which is prepared in example 1, after 15 parts of acryloyloxy propyl trimethoxysilane and 1.5 parts of di-isopropoxy aluminum ethyl acetate were added and mixed, 9 parts of ion-exchanged water was added. The mixture was cooled to room temperature after reacting for 8 hours at 60° C. and 1.8 parts of acetyl acetone was added. While MI BK (methyl isobutyl ketone) was added so that the total solution amount is substantially uniform, the solvent was replaced using evaporation at reduced pressure. Finally, a dispersion solution B-1 was prepared by adjusting so that the solid content is 20%.

[0510]Preparation of Hollow Silica Dispersion Solution A-2

[0511]A hollow silica particle dispersion solution A-2 (solid content concentration of 18.2 mass %) where the average particle diameter was 50 nm, the shell thickness was 8 nm, and the refractive index of...
